Hi!

Do you guys know of any processor/microcontroller with an on-chip digital-to-analog conversion?

Yes, I know that one way to implement a D/A converter is by taking a PWM output line through an external low-pass filter. However, if there's a controller that gives analog output directly, please let me know.

Regards,
Vesa ;-)

Cypress PSOC and/or TI 430?

From the data sheet:

Quote:
The AT90PWM2/2B/3/3B features a 10-bit Digital to Analog Converter. This DAC can be used for the analog comparators and/or can be output on the D2A pin of the microcontroller via a dedicated
driver.

Great, thanks for educating me! :-)

I looked up those 3 processor families and saved one data sheet of each as reminder for future need.

Analogue devices also do some MCU's (8052 -urgh and ARM7TDMI) with DAC's on them...

(am I in the sin bin now?)

Some NXP ARM chips (like the LPC2148) have a DAC.

I saw one (leaked?) spec sheet for AVR's upcoming XMega 8-bit family. There is a line of MCUs there have an integrated DAC.
